Abstract
Waterborne polyurethane (WPU) which is environment friendly has been rapidly used in coating and adhesive industries. However, the WPU is deficient in chemical resistance, thermal resistance, and mechanical property compared to solvent-based polyurethane. In this study, the WPU was synthesized from two types of polyester polyols, 4,4-dicyclohexylmethane diisocyanate (
친환경적인 수분산 폴리우레탄은 코팅, 접착제 등의 분야에서 급속하게 사용되어지고 있다. 하지만 수분산 폴리우레탄은 용제형 폴리우레탄에 비해 내화학성, 내열성, 기계적 물성 등이 떨어져 이를 개선하기 위한 연구가 활발히 진행되고 있다. 본 연구에서는 polyester polyol, 4,4-dicyclohexylmethane diisocyanate (
